.'l`o all whom it may Concern:

le it known that we, EDWARD THOMAS Pennino, engineer, a citizen oi the United States, and EMIL Lno lfnnnMANN, engineer, a subject o the King oi ltoulnania, both residing at 3o' l `eatherstone street, London, England, have invented a certain new and useful (lig-.trolte-Paeking Machine, of whit-li theriollowing is a spmfilieation.

This invention relates to improvements in machines lor making boxes er cases from. a web ol paper or card and lilling them with. cigarettes or othei` articles, the paper 'ol a width sullieient to inake the box required being drawn oil', printed in one or more eolors, and

oi a series ol molds formed transversely across the cirennilerenee el' an intermittently rotated wheel, in which the box is l'ormed, lilled and closed.

Figure l of the drawings isa side 'View oi part ol' the niaehine; and Fig. l isaside view el the other part thereof. li ig. 2 is an end view ol' the machine. Figs. 3, 4 and 5 show details ol the die and the paper ieed mechanisrn. Fig. (l sliowsthe method oi driving the mold wheel. Fig. (3 is an edge View oi a portion oi this wheel. vliigs. 7 to ll show detailsof the lirst leiding Ineehanisin. Figs. l2 and 13 show details ol the meehanism l'or pasting the sides o1' the boli. Figs. 14 to 2O show details oi' the meehanisni lor Iilling the box with Cif rettes. Yliigs. 2l. to 2-1 show details of the mechanism for closing the box, and Figs. 25 to 3l. show the box in its various stages. O these lignres l to (i, 6, l2 and '11j are te one scale, Figs. 7, 14, l5 and 2l to 24 are to a larger scale, Figs. 1G to 2() and 25 to 3l are to a larger scale, and i"igs. S to ll are to a scale again larger. l is the main shalt driven from the shalt 2 litted with a belt pulley 3. On the shalt l is a earn Llroeking a lever 5 which draws oli paper troni the rollo. ln the machine illustra ted the paper passes' through a printer 7, brenner S, polisher 25X, and printer i) bynhieh it is printml in two colors and bronned. All these are olf onlinaryl eo1\striu:ti. n and need no deseription; they are all driven. :troni the shalt l. The paper thus printed passes beneath a .fixed plate l() against whieli it is pressed by a die ll. whieh receives a vertically reciprocating movement from a pair ol' eeeentrics l2 (see Fig. 3) on cross shafts i3 and i4 driven from the shalt l by bevel gear.

the paper should be fed forward With great precision Vinst the length of a blank for each movement oi the 'mold wheel and this is effected as follows-A slide 15 moving on guide rods lli receives a to and iro horizonta'l movement rom a link 1 7 one end of which is conf :nected to a pin on a crank 18 on the shaft 13 While its other end is pivoted to the slide at 19. The web 6 is gripped between a fixed jaw 20 and a jaw 21 held up to the jaw 20 by a spring during half the revolution of the crank 1S but at the proper time owing to the rotation of lthe crank Whose throw is equal to the length of a blank the link 17 turns on the pivot ll) and a linger 22 on the link presses on a roller 23 carried by the jaw 2l, and pulls the ijaw down to release the paper. The forward end ol the slide carries a pair oi hooks 24 which. catch hold oi the leading blank behind the baeli `flaps g and pull it forward.

The scoring, cutting and folding operations are precisely the same as those shown and described in U. S. Patent No. 775,148, granted to Edward T. Pollard November l5, 3901i.

The die ll (which is of the kind shown in said pat ent) is so lorrned that it does not sever the top flap of the leading blank from the baeli of the next until the leadingI blank is inposition beneath the mold Wheel. 25.

On each upward stroke oi the die the leading blank is severed iroin the second and thrust inte a mold while the second blank is scored and eut but not sev ered ironr the web. This mold wheel turns on trunnions Z6 supported by brackets 27 which also Carry a slirouding 28 which covers in the wheel.

The wheel is moved round clockwise when viewed as in Fig. 2 by means of a crank 29 on a Way shaft 30 driven off the shaft 14. rl`he crank. is connected to a link 3l, whose upper end is slotted and embraces the inner trunnion 2li. On the link a pawl 32 which enters slots fili on the inner iaee oi' the Wheel and turns it one step ier eaeh revolution oi the main shalt see Figs. (i and 43"..

The upward movement oi the die forces the blank into that mold 311- wlxieli is at the bottoni ei the wheel, the mold being just large enough :lor the iront a. of the box to'lie llat against its bottom while the sides/1:" against its sides. The back llaps are also bent slightly by the baek being forced into a shallow .mold carried by the shrouding, the llaps thus assuming positions approximately at right angles to the back. As tbe die eomes down a blade 36 is slidden horizontally to the righi see Fig. 7 to hold the blank in its mold and prevent its following the die. the blade by a bell crank 37 and earn groove 36 on the shaft l.

When the wheel has turned through an angle of the blank arrives at the lolding mechanism shown in Movement is imparted to, l

Figs. 7y to 11u and the leading back flap g, which as al- 'ready stated, is in avposition approximately at right angles to the back, comes against a fixed plate 39. A link T40, a pin 41 on which moves in a slot 42 in the framing is f reciprocatedtby a cam 43 on the shaft l. The lower i endof the link is connected by a rod 44 to a fixed comes against the following back flap g and bends it .wv-also at right angles to the back, the plate 46 coming l .stifliciently near to the plate 39 to pinch as it were the back e and flaps g together so that the blank is now in the position shown in Figs. 274 and 28. At this point the sides f are pasted on their insides 4as follows1 A saddle 47 reeiprocated on guide rods 48 by a link 49 from the lever 5 (see Fig. 1) carries a pair of arms 50 (see Figs. 12 and 13) having at their ends rollers 51. .'lhese rollers normally rest against the rim of a wheel 52 dipping into a paste box zandicarried by a stud axle 54 rotated by a shaft 55 driven by the shaft 1. As

soon as the pastey has been applied to the sides by the rollers 5l the bottom d and back c of the box are .folded over by the mechanism shown in Figs. 8 to l1. A plate 5G secured to the shrouding carries a stud axle 57 rocked by bevel gear from a spindle 58 on which is a pinion 59 (see Fig. 7) gearing with a rack G0 on a rod G1 carrying a bowl 62 running on a cam 63 on the shaft 14. Fast with the axle 57v` is a wiper 64 consisting of two parts at right angles the outer part being eut away as shown in Fig. ll which is a view of the wiper in the position in which it appears in Fig. 9 looking as in Fig. 2.- Pivoted at 65 to the plate 56 is a folder 66 constantly urged to the positionin which it appears in Figs'.- 8 and 10 by the coiled spring 67 against which it is pulled back by the wiper 64. Pivoted at 68 to the folder is a plate 69 which has upon it a hook 70 surrounding the end of the wiper 64. The first movement of the spindlefrom the position in Fig. 9 allows thespring 67 to tum the folder 66 on its pivot to the' plate 56. The folder in this movement has turned the` bottom d from the position in Fig. 28:' to that inv Fig. 29 while the plate (59 has turned the back c through a similar angle and the further movement of the wiper 64 compels the plate 69 to continue its movement to the position shown in Figs. 8 and l0 which completes the movement of the back into the position shown in Fig. 29, the back flaps g passing by reason of the squeezing action of the plates 39 and 4G just inside the .sides f to which'they are lie/ld by the paste thereon while the bottom flaps h lie just inside the bttom see Fig. 29. The wheel now moves on one step and at its next stop airiron 7l. carried by tht.y saddle 47y and heatedin its backl position by a Bunsen burner or other convenient means/enters the box to dry. the

paste. At' the next lstop'a pairl of pressing rollers 72 `imilar to the pasting rollrs enter the box and press 'the hack flaps against tlre"sides. 73 is a further pair of pressingrollers. "llllelbox next arrives at the filling mechanism showniin Figs. 14 to 2,0.

6tlg 74 a hopper filled with cigarettes and reciprocated toy prevent the cigarettes sticking above a filler 75 by a linlc"'76 (see Fig.i2) from a long bell crank 77 lwhose lower end carries a bowl 78 moved by a cam :von the shal't l. .lhe filler 75 is divided into five or other number of chambers each wide enough to hold front a at once the top flap would miss the slit i.

.one cigarette by vertical partitions 76 the bottoms of which are cut away in front as seen in Fig. 14 to allow the cigarettes to close up as they are pushed forward.

Beneath the filler is a tray 77 seen in section in Figs. 16 and 17 in plan in Fig. 18 and from the rear in Fig. 19 and constantly pulled towards the mold wheel or box holder by a spring 79 but drawn back while the wheclis moving by a series of pushers 80 carried by the saddle 47. The front of the tray carrieslight'blade springs 81 at cach side which enter the box while a flap 82 is pivoted at' 83 to the tray so that when the .tray is back it is held up as seen in Fig. 16 owing to its back edge passing beneath a fixed incline 84; as the tray moves forwardthe flap is released from this incline and tilts forward by its own weight as shown in Fig. 17 being stopped by lugs 85 coming against shoulders 86 on the tray. The front of the flap'thus enters the box beneath the back e and prevents the iront ends of the cigarettes catching thereon.v The whole action is :is followsz-lhe chambers of the filler are kept filled with cigarettes owing to the shaking of the hopper. When the wheel stops the parts are in the position shown in Fig. 1G but on the saddle moving forward the pushers allow the spring todi-aw the tray forward tothe position in Fig. 17 and the springs and flap enter the mouth of tho box; the continued movement of the pushers pushes say the lowest two cigarettes in each chamber into the box and the -pushers yand tray then recede. The outer sides of the two outer pushers are formed of a wedge shape so as to cause the forward ends of the push-l ers to close up as they advance so as to exactly follow the cigarettes which are brought together bythe springs 8l. 'lhebottom ol' the tray is cut awayas shown and a channel 87 is provided fo the escape of any tobacco dust which might clog the mechanism. The filled-box now comes to the mechanism for closing the box and tucking the end of the top flap into the slit i inthe back. This is shown in Figs. 2l to 24, 2l being a side elevation' t'. c. a vicw similar to Fig. 1, 22 an underside view, 23 a view of the far side of part of the mechanism seen in Fig. 21. 88 is a pusher carried by the saddle 47 and having pivotod to it at 89 a lever 90 whose tail isheld in the position shown in Fig. 22 by a blade spring 91 on tho pusher. As the pusher advances the tail of the lever encountersa projection 92 carried by the shrouding of the mold wheel which causes the lever to turn slightly on its pivot. 0n each side of the lever is a shoulder 93 fixed to the pusher. The pusher in its for-` ward movement meets the top flap c and pushes it towards the left as in Figs. 2l and 22. Supposing however that the top b were to close in at right angles to the It is therefore necessary to hold back the top b as shown in Fig. 30. This is effected by two small lugs 94 carried' by a pair of jaws 95 pivof'ed at 96 to a plate 97 (see Figs. 2 and 24) carried by the shrouding of the mold wheel. These jaws are normally hold up to stops 98 by a spring 99 but as the pusher 88 advances inclinos 100 uponfit cause the jaws to open against the spring 99 so as to withdraw the lugs 94 from the mouth of the box. The action is as follows-The box stops opposite the pusher with its top and top flap occupying the position shown in dots in Figs. 22 and 3() these parts having been brought into this position by a slot inthe far side of the shrouding of the mold wheel. The pusher S8 moves towards the mold pushing the top flap and top before it; the top is however arresterl by the ings 94. and the top fiap is pressed down onto the back. As the pusher continues its movement the lever 90 is turned on its pivot and presses the top Hap down onto the back which is thus bent opening the slitl 1l, the jaws J5 are opened withdrawing the 'lugs 94 and the Shoulders 93 press the top b home as shown in Fig. 3]., the end ol' the top (lap'e entering the slit i and closing the box. i
